The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Hazira, Surat. Operators at Hazira include international energy companies alongside Indian majors, and their contractors move between sites. IECEx evidence, meaning a certificate of conformity with its schedule of conditions, gives a shared reference. SAMS is pursuing it for the IS-04Z1, and nothing has been issued.

Questions · Hazira India
Frequently asked questions
Can we buy an IECEx mobile phone in Hazira India today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an IECEx mobile phone in Hazira India cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Hazira, Surat would use it?
Likely candidates are lng regasification, gas processing, petrochemical plants, marine terminals. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
How long is the transfer from Surat to Hazira?
Hazira is 22 kilometres from Surat and the drive takes about 30 to 35 minutes. Most visitors fly into Surat, and heavy plant traffic and monsoon rain can slow the road.
What mix of hazardous areas does Hazira have?
Hazira combines an LNG terminal, gas and power plants, a manufacturing division and a shipyard, so it has gas-hazard zones, hot-work areas and mixed-use industrial zones. Always get the area classification and equipment rules from the specific operator.
Who sets the rules for carrying a handheld into an LNG terminal at Hazira?
The terminal operator does, through its permit and area classification system, with PESO as national regulator. Rules usually cover approved equipment, permits and charging. Ask the operator's safety team what evidence they need from a supplier before a new handheld may enter.
